If you are a British owner who lets a furnished flat or house in France, Brexit does not create a separate tax category. France looks first at the property, the nature of the letting and your tax residence. The rent may fall within French b\u00e9n\u00e9fices industriels et commerciaux<\/em> (BIC), meaning industrial and commercial profits, rather than revenus fonciers<\/em>, the category used for most unfurnished lettings. The choice between the micro-BIC<\/em> flat-rate regime and the r\u00e9gime r\u00e9el<\/em> actual-expense regime then affects your forms, deductions, accounts, social charges and exposure to a correction.<\/p>\n

This article concerns an individual British owner and an existing French property. It does not cover buying the property, forming a company or transferring the property into a French soci\u00e9t\u00e9 civile immobili\u00e8re<\/em> (SCI<\/a>). It focuses on the practical legal question that follows the first booking or tenancy: what must be registered, declared and retained when the owner lives in the UK, moves to France or changes residence after Brexit?<\/p>\n

The answer depends on facts that are often hidden by a letting platform statement: long-term furnished tenancy or short-term tourist letting, joint ownership, income level, French residence, UK residence, mortgage and repair costs, the use of an agent, social-security affiliation and the municipality where the property is located. The safest approach is to classify the arrangement before copying any total into a return. The broader cross-border filing sequence is covered in our guide to UK rental income and France after Brexit<\/a>; this article supplies the furnished-rental branch that requires a different analysis.<\/p>\n<\/div>\n

I. How is French furnished rental income taxed for a British owner after Brexit?<\/h2>\n

A. Does France tax the rent, and when does a furnished letting become BIC?<\/h3>\n

The property is the starting point. Article 6 of the 2008 UK\u2013France double-taxation convention in force<\/a> states that income from immovable property situated in a contracting state may be taxed in that state, and expressly applies the rule to income from letting. The convention was published in France by Decree no. 2010-20 and the treaty of 19 June 2008<\/a>. A French property therefore remains within France\u2019s taxing jurisdiction even when the owner is British, the rent is paid into a UK account and the letting agent is based in London.<\/p>\n

For a British owner who is not French tax resident, Article 164 B of the French Tax Code<\/a> identifies French-source income. Its first category includes the words \u00ab Les revenus d’immeubles sis en France ou de droits relatifs \u00e0 ces immeubles \u00bb<\/em>. In English, income from buildings situated in France, or rights relating to those buildings, is French-source income. A non-resident cannot turn a French letting into foreign income merely by receiving the rent abroad.<\/p>\n

Residence changes the wider reporting picture. Article 4 B of the French Tax Code<\/a> treats as fiscally domiciled in France people who have their home or principal place of stay there, who carry on their main professional activity there or whose economic interests are centred there, subject to an applicable treaty residence result. The statutory wording begins \u00ab Les personnes qui ont en France leur foyer ou le lieu de leur s\u00e9jour principal \u00bb<\/em>. A British owner who has recently moved to France should establish the residence date and keep evidence of the household, days spent in each country, work, family and financial centre. The certificate and correspondence process is separate from the tax classification of the rent; our article on obtaining a French residence certificate for HMRC<\/a> can be used for that issue.<\/p>\n

French domestic law then asks whether the accommodation is furnished. Article 35, I, 5 bis of the French Tax Code<\/a> classifies as BIC the people who give furnished residential premises for direct or indirect letting. The operative words are \u00ab Personnes qui donnent en location directe ou indirecte des locaux d’habitation meubl\u00e9s \u00bb<\/em>. BIC is a French tax category, not a statement that the owner has incorporated a business in France. A private landlord can be a loueur en meubl\u00e9 non professionnel<\/em> (LMNP), meaning non-professional furnished landlord, while still having to register the activity and file the relevant professional-income forms.<\/p>\n

Furniture must support normal occupation, and the length and service level of the letting matter. A furnished tenancy used as a tenant\u2019s main home is not analysed in the same way as a succession of nightly bookings. A platform\u2019s label, the English expression \u201choliday let\u201d or the fact that the owner lives in Britain does not settle the French category. Prepare the inventory, tenancy terms, advertising, booking calendar, cleaning and service invoices, and the actual use of the premises. Those documents can decide whether the activity is long-term furnished letting, a furnished tourist letting or something that needs a different analysis.<\/p>\n

Short-term tourist use brings a second layer of law beyond tax. In its decision no. 19-13.191 of 18 February 2021<\/a>, the Third Civil Division of the Cour de cassation examined repeated short rentals of a Paris dwelling. The verified passage states that repeated letting for less than a year to passing occupants who do not make the premises their main home \u00ab constitue un changement d’usage d’un local destin\u00e9 \u00e0 l’habitation et, par cons\u00e9quent, est soumis \u00e0 autorisation pr\u00e9alable \u00bb<\/em>. That is an authorisation rule, not a tax exemption. A British owner must check the municipality before relying on a tourist-letting business model.<\/p>\n

The registration rule is also enforceable. In decision no. 23-13.567 of 27 June 2024<\/a>, the Cour de cassation confirmed that, subject to the residence-principale exception, a person offering a tourist furnished property must have made the prior declaration to the mayor. The verified wording is \u00ab toute personne qui offre \u00e0 la location un meubl\u00e9 de tourisme, que celui-ci soit class\u00e9 ou non au sens du code susvis\u00e9, doit en avoir pr\u00e9alablement fait la d\u00e9claration aupr\u00e8s du maire de la commune o\u00f9 est situ\u00e9 le meubl\u00e9 \u00bb<\/em>. In practice, keep the declaration number, municipal authorisation, registration receipt and correspondence with the mairie, which is the town hall.<\/p>\n

The treaty does not erase these domestic obligations. It allocates taxing rights between France and the UK; it does not decide whether a flat may be used for repeated tourist stays, whether a declaration was required or whether the rent is BIC. If the UK also taxes the income because you remain UK resident, Article 24 of the convention supplies the double-tax mechanism. The country of residence and the country where the property is located may both appear in the calculation, but the same amount must not be treated as if it were two unrelated businesses.<\/p>\n

B. Should you choose micro-BIC or the r\u00e9gime r\u00e9el, and what other charges follow?<\/h3>\n

The principal choice is between the flat-rate micro-BIC regime and the actual regime. The current text of Article 50-0 of the French Tax Code<\/a>, in force from 1 July 2026, sets the micro thresholds and allowances. For the general category covering ordinary furnished letting, the text gives a limit of \u20ac83,600 and a 50% allowance; it gives a separate \u20ac15,000 limit and 30% allowance for non-classified tourist furnished accommodation. The statute says, for the general category, \u00ab 83 600 \u20ac s’il s’agit d’autres entreprises \u00bb<\/em> and provides that the result is the turnover reduced by the relevant allowance.<\/p>\n

Year matching is essential. The French administration\u2019s page on furnished lettings<\/a> and its page on tax regimes<\/a> still show the figures applicable to 2025 income, including \u20ac77,700 for ordinary furnished letting and \u20ac15,000 for non-classified tourist furnished accommodation. Those figures are used for a 2025-income return filed during the 2026 campaign. The current statute applies its own threshold to the relevant income year. Write the year at the top of the calculation, then check the statutory text and the administration\u2019s form for that year rather than carrying last year\u2019s threshold forward.<\/p>\n

Under micro-BIC, you normally report the gross receipts, including charges paid by the tenant, and the administration applies the fixed allowance. You do not deduct the agent\u2019s commission, furniture replacement, mortgage interest or repairs a second time. The official answer on including charges<\/a> confirms that the amount declared includes rent and relevant tenant charges. Your ledger must therefore distinguish the gross amount received from the net amount that reached your bank account.<\/p>\n

The r\u00e9gime r\u00e9el can be preferable where actual costs are high, particularly when there is significant interest, qualifying repair work, insurance, management cost or accounting depreciation. It requires a result declaration, generally Form 2031, and an accounting file. The official guidance explains that actual charges must be incurred in the activity\u2019s interest, supported by sufficient evidence and recorded in the correct accounting period. Depreciation can be deducted only within the statutory limits; it cannot be used as a shortcut to manufacture an unrestricted deficit. The comparison should be made on a year-specific French calculation, not by translating a UK property schedule line by line.<\/p>\n

The administration also states that a property held in indivision cannot use the micro regime and must be declared under the real regime. Indivision means that two or more people own the property directly in undivided shares. That point matters for British couples, siblings and estates: the ownership document, the beneficial shares and the rent-allocation agreement should be reconciled before a return is filed. A platform statement naming one person as host does not prove that person is the sole French taxpayer.<\/p>\n

LMNP and professional furnished landlord status are distinct from the micro-versus-real choice. The current administrative explanation<\/a> uses two cumulative tests for professional status: annual receipts above \u20ac23,000 and receipts exceeding the household\u2019s other income in the relevant categories. The test is made at household level and applies to the furnished lettings together. A British owner should not describe the activity as \u201cprofessional\u201d simply because it has a SIRET number, and should not describe it as \u201cprivate\u201d merely because there is one flat.<\/p>\n

Case law shows why gross receipts, net BIC and professional status must not be collapsed. In Cour de cassation, Commercial, Financial and Economic Division, decision no. 22-17.612 of 20 December 2023<\/a>, the court considered the professional furnished-letting test in an ISF context. After checking the complete decision through Judilibre, the relevant passage refers to \u00ab le b\u00e9n\u00e9fice industriel et commercial net annuel d\u00e9gag\u00e9 par cette activit\u00e9 \u00bb<\/em>. The decision concerns the former wealth-tax provision and should not be copied mechanically into today\u2019s income-tax computation. It is, however, a useful warning that the legal question may require net BIC rather than an agent\u2019s gross-receipts total.<\/p>\n

Social charges are a separate calculation. Article L. 136-6 of the Social Security Code<\/a> covers income from property and BIC within the contribution on income from assets. Its opening rule says \u00ab Les personnes physiques fiscalement domicili\u00e9es en France au sens de l’article 4 B du code g\u00e9n\u00e9ral des imp\u00f4ts sont assujetties \u00e0 une contribution sur les revenus du patrimoine \u00bb<\/em>. The current impots.gouv.fr guidance<\/a> states 18.6% for furnished letting on the net amount, while also explaining that a person affiliated to the health-insurance system of the European Economic Area, the United Kingdom or Switzerland and not covered by a compulsory French system is not liable for CSG and CRDS on property income, although the solidarity levy may remain due.<\/p>\n

That exemption is evidence-driven. A British passport, a private health policy, an S1, National Insurance contributions or a French residence card does not by itself identify the applicable social-security legislation for the rental period. Obtain the official affiliation evidence, identify whether a French compulsory scheme covered you, separate CSG and CRDS from the solidarity levy, and check the box used for the particular income year. If the administration has charged the full amount, the claim should identify the exact period and the legal basis for the requested correction.<\/p>\n

Finally, check the cotisation fonci\u00e8re des entreprises<\/em> (CFE), a local business tax. The furnished-letting guidance states that an owner generally must file the initial Form 1447-C-SD by 31 December of the first year of the activity, with exceptions for certain occasional or personal-home situations. Article 1647 D of the French Tax Code<\/a> also deals with the minimum CFE base. For an overseas taxpayer carrying on a property rental activity in France, it places the minimum at the location of the French property with the highest rental value. The text refers to \u00ab Les redevables situ\u00e9s \u00e0 l’\u00e9tranger qui r\u00e9alisent une activit\u00e9 de location ou de vente portant sur un ou plusieurs immeubles situ\u00e9s en France \u00bb<\/em>.<\/p>\n

The current statute provides an exemption from the minimum contribution where turnover or receipts do not exceed \u20ac5,000, but local rules, the nature of the activity and other exemptions must still be checked. CFE is not the same as income tax, taxe fonci\u00e8re or taxe d\u2019habitation. Keep the CFE notice, the 1447-C filing, the property address and the municipal calculation in a separate file. A furnished-rental tax return can be correct while the CFE declaration is missing.<\/p>\n

II. Which forms, deadlines and remedies should a British furnished landlord use?<\/h2>\n

A. How do you file in France and report the same property in the UK?<\/h3>\n

Build the filing calendar around the property\u2019s French income year and your UK residence status. France normally works on a calendar year. The UK tax year runs from 6 April to the following 5 April. A British owner who lives in the UK may have to report French rent as foreign property income on the UK return. A British owner who is resident in France may still need to deal with HMRC if the residence rules, a prior UK period or another UK connection keeps a UK filing obligation alive. The GOV.UK guide to foreign income<\/a> says that UK residents normally pay UK tax on foreign income and that overseas property rent is taxed through the normal rules.<\/p>\n

On the French side, start with the activity registration and the right income form. A furnished activity normally requires a declaration through the formalities portal so that a SIRET number can be issued and the chosen tax regime recorded. The first-year CFE declaration is separate. The annual income return will normally involve Form 2042-C-PRO for LMNP income, with Form 2031 and its schedules if the real regime applies. The exact boxes change with the year and with the professional or non-professional classification. Do not use the boxes for French unfurnished property simply because the English tenancy agreement calls the house a \u201clet\u201d.<\/p>\n

Where the income is foreign for the person filing in France, Form 2047 may also be relevant, but a French property rented by its owner is not foreign-source income merely because the owner is British. A UK-resident owner may need Form 2047 to declare foreign income in the French return only if France treats that person as resident or another French reporting rule applies. The source rule, residence rule and form instruction must be read together. The form cannot change Article 164 B or Article 4 B.<\/p>\n

On the UK side, the official Self Assessment Foreign (SA106) page<\/a> says that the supplementary pages record foreign income and gains and can be used to claim foreign tax credit relief. If you remain UK resident and France has taxed the French rent, preserve the French assessment and proof of payment for the UK claim. If the French result is reduced by the micro-BIC allowance, the UK foreign-income computation may still use different UK rules. A French tax credit is generally limited by the UK domestic rules and the treaty method; it is not automatically the full amount shown on a French notice.<\/p>\n

Article 24 of the UK\u2013France convention<\/a> deals with elimination of double taxation. For a UK resident who is taxed in France on French property income, the UK-side mechanism generally requires a foreign-tax-credit analysis. For a French resident, the treaty may leave income taxable in France because the property is there, while another item of UK income can follow a different rule. The convention is not a general \u201cBrexit exemption\u201d. It is a map of which state may tax and how the second charge is relieved.<\/p>\n

Keep currency conversion transparent. A UK agent may report sterling receipts, commission and expenses by UK tax year, while the French return needs euros and a calendar-year total. Record the date and amount in pounds, the conversion rate used, the euro result and the source of the rate. Keep the bank statement and agent statement together. If the rent was paid into a joint account, identify the beneficial owner and the agreed share rather than dividing it casually by two.<\/p>\n

A useful reconciliation table should contain, for each property:<\/p>\n
